' SASH-LOCK.

Specification of Letters Patent.

Patented Oct. 5, 1920.

Application filed January 7, 1920. Serial No. 349,966.

T 0 all to hom it may concern:

Be it known that I, SAMUEL SEGAL, a citizen of the United States, and resident of the city of New York, in the county of New York and State of New York, have invented a certain new and useful Sash-Lock, of which the following is a specification.

This invention relates to sash locks for the type of windows wherein an upper and a lower sash guided in ways are slidable upwardly and downwardly for opening and closing the window, and the invention relates particularly to those sash looks that are intended to lock the window sashes when they are either in closed state or in partially opened position. 7

The principal object of my invention is to provide a simplified, inexpensive, strong, durable, and improved sash lock of the above type, that can be conveniently and economically manufactured and sold'at low cost, that can'be conveniently and rapidly installed by the purchaser, and that can be operated conveniently and efficiently after installation to lock the sashes in any position and to be rendered inoperative.

Other objects and advantages will hereinafter appear.

In the accompanying drawings,

Figure 1 is a vertical section of the sash lock on the line 1-1 of Fig. 2;

F 2 is a plan view of-the sash lock.

Fig. 3 is a vertical cross-section of the lock on the line 3-3 of Fig. 1.

An upper window sash 1 and a lower window sash 2 are framed within guide ways of the window-frame, not shown, whereby they are slidable upwardly and downwardly for opening and closing the window to agreater or lesser extent. The base '3 of the sash lock comprises an upright portion or post having a pair of extensions 5 with openings 6 therein through which suitable screws may be passed and threaded into the top rail of the lower sash 2, to which the sash lock is secured in this manner when installed for use. 7 Said base. is preferably made of cast metal, and in the casting operation thereof a threaded bar 7 is inserted thereinto, whereby in the completed base a portion of the bar is fixed within the post 4:, or rigidly secured thereto, and the remainder of this bar extends, as a threaded bolt, from the base, in a direction away from the upper sash 1 when the base is installed in operative position. upon the base 3 comprises a front plate 9, from which extends a horizontal plate 10 and a pair of upright plates 11. The front plate 9 is provided with an opening 12 wherewith the carriage is slipped over the bolt 7 in the assembling of the lock, the plate 10 is located in a channel 13 formed in the underside of the base 8, and the plates 11 are located adjacent the sides of the post 1 of the base, whereby the carriage 8 is rendered slidable toward and away from the upper sash 1, and is guided in its movement by the plate 10 against upward or downward dislocation, by the plates 11 against lateral dislocation, and by the passage of the bolt 7 through the opening 12 of its front-plate 9 for the general maintenance of its proper alinement upon the base 3. Said carriage is preferably made of a single piece of sheet-metal and is bent to its re quired form out of a flat blank by suitable stamping operations. and the extremity 10 of each of its plates 10, 11 is preferably bent right angularly in the manner shown so as to provide a firm holding surface when in contact with the sash 1. A coiled spring 14 encircles the bolt 7 and bears against the post 1 and the front-plate 9 of the carriage, and in this manner normally tendsto more: the carriage away from the upper window-sash 1. The bolt 7 carries a thumb-screw 15 which. threads thereover, and between said thumb-screw and the front-plate 9 of the carriage is located a sleeve 16 which surrounds the bolt. V

In the installation of the lock, the base 3 thereof is fastened or secured by means of screws 17 to the top of the lower sash 2 opposite to the vertical rail of the upper window sash 1. lVhen it is desired to lock the window, with its sashes in either closed or partially opened position, the thumb-screw 15 is threaded forwardly toward the upper sash 1 until it is in a tightened condition, whereupon the thumb -screw 15 presses forcefully against the sleeve 16 which in turn bears against the carriage 8' and compels it to exert strong pressure of itsplate-extrem ities 1O against the upper sash 1 to thereby lock it together with the lower sash firmly in place, by the simultaneous binding action of both the upper and lower sashes against their guide ways in the windowframe. To unlock the sashes it merely re- A carriage 8 mounted quires unthreading of the thumb-screw '15,

which operation releases all of the parts of the lock and the spring 14: thereupon forces the carriage 8 to move awayv from the upper sash to entirely clear the same and render g nomical manufacture thereof, so that the lock may be sold at very low cost. I r Variations may be resorted to within th scope of the invention. I

Having thus described my invention, I claim 2' V 1. A sash lock having the combination of a'base secured to a window sash, a bolt fixed to said'base, a movable carriage on said base anda nut threading over said fixed bolt and bearing against said carriage whereby said carriage may be forced against a second window sash.

2. A sash lock having the combination of a base secured to a window sash, a bolt fixed to said base, a movable carriage on said base, a nut threading over said fixed bolt and bearing against said carriage whereby said car riage may be forced against a secondwindow sashand means adapted to move said carriage away from said second window sash upon the unthreading of the nut.

3. A sash lock havingthe combination of a base securedto a window sash, a bolt fixed to said base and projecting therefrom, a

movable carriage slidably mounted on said base and guidedin-its movement by saidbase andbolt and a nut-threading over said fixed bolt and adapted, to force said carriage against asecondwindo'w sash.

A sash lock having the combination or a base secured to a window sash, a bolt car- 'riedby saidbase, a movable carriage Sl1Cl-' ably mounted on said base andguided in its movement by s'aidbase,a nut carried by'said bolt for forcing said carriage against a second -window sash, means tending to move said carriage away from said second window sash and a sleeveon said bolt intermediate said nut and carriage permitting manipulation of said nut remote from said window sashes.
